Right now I'm using a single GTX260 @ 710Mhz core/1200MHz memory on a 1680x1050 monitor. I can pick up a used GTX260 for a little over $100. Would I see much of a performance gain to be worth it? I mainly play BC2 and a few other games less frequently. I would have to use the sli patch to run it on a P45 board bear in mind.
